' the yparts normally occupy the position .illus` trate'd in Fig. 1,'in which the piston ,is posi,- tioned between the port 15 and the two ports 16V and 17 which in consequence are all unfA cove-red, the-'electrodes 8 and 10 aresepa-v rated, the valve-23-closes the exhaustport 17, the admission port 16 is uncoveredvby the valve 22 and the'solenoid27'1is dener,` git/led. The parts are held in. this position by-- the action o the spring 28 until the' compression of thecharge'in the cylinder 2 causes' a portion ofthe compressed gases to 'enter theY part of the piston chamber behind-the piston along a course which includes the openings 9, the interior of the member-6, the passage -21the valvechamber 18 and the admission l so.

The lpiston is in consequencev moved ""'Whi'ch it closes the air'inlet port ,15.1 The ,pressed to return 'the postim when the charge of compressed air which was previously admitted to the piston, is. b vmovement of the latter com`v gases at its opposite side is exhausted. This'` takes vplace when `by energization joffthe solenoid through' the mediumof the'` conf .I stantly *rotating timer 31., its core '26@ i's'I moved" inwardly against the laction of `the sp1'ing28 and the position of the two valvesf,

is consequence reversed to respectively' Iclose the admission port 16l and openthe eX-,S l haust port 17. The'co-mpressed air in front a i ofthe piston` in co-a'ctionvwith thecorn" pressed gases admitted through the rfpfiS'sage,`

` formed' .by the1 flattened portion 29 'of the'l lmovableelectrode, causesA the piston tov move.
